ELECTRICAL INTERLOCKING MECHANISM FOR SWITCHES AND SIGNALS.

SPECIFICATION forming part of Letters Patent No. 357,109, dated February 1, 1887.

Application filed Angnst 7, 1586. Serial No. 210,266. (No model.)

Fig. 23, Sheet 14, shows in side elevation a portion of the lock mechanism operated in connection with the signals, the scale of drawing being the same as Fig. 22. Fig. 24, Sheet 15, is a vertical sectional view to the same scale as Figs. 22 and 23, the same being illustrative of locking mechanism controlled by circuits made and broken by movement of the signal-motors. Fig. 25 is a view in sectional elevation of detached portions of a sliding bar, a lockingplate, and the electrically-controlled mechanism employed to effect locking engagement between the plate and sliding bar. Fig. 26, Sheet 16, is a vertical sectional view of one of v the electrically-controlled fluid-pressure motors employed to operate signals. Fig. 27 is a view in elevation of one of the motors, Fig. 26, connected to a signal and signal-post for the purpose of operating the signal to indicate "danger and safety, the normal or danger position being shown. Fig. 28, Sheet 17, is a diagrammatic view of a portion of a track with switches and signals and portions of my-present invention applied to operate such switches and signals, the same being illustrative of the principles and operation involved in' applying my invention to practical use; and Fig. 29, Sheet 18, is a diagrammatic plan of an insulated section of track with a signal and circuit, illustrating a modificationof a portion of my invention.

My invention relates to interlocking mechanism for operating switches, signals, looks, I and other mechanism or appliances relating to Fig. 22, Sheet 13, is a front 6:

movements of trains on railroads; and,in general terms, it consists of certain combinations of fluid-pressure motors for operating switches or some part of or appliance connected with the track, valve mechanism for directing fluidpressure upon a liquid column at a distant station to operate the motors in either direction, interlocking mechanism for operating the valves of a seriesor' number of such motors in some predetermined order, electrically-controlled mechanism for locking the interlocking apparatus at intermediate positions, and electric circuits for controlling the intermediate locking mechanism, such circuits being made and broken both in the preliminary movements of the valve mechanism of the motors and also at the completion of their pistonstroke, electrically-controlled fluidpressure mechanism for operating signals, circuits controlling the signalmotors', made and broken both individually and in sets by the interlocking apparatus, and also by movement of the locking mechanism, electrically controlled mechanism for securingthe interlocking apparatus in positions for operating signals, and electric circuits controlling such locki ng mechanism, such circuits being made and broken by operation of the signal-motors, as hereinafter more fully described and claimed.

The present invention is shown in the drawings in the form of a six-lever machine, the several parts and proportions being arranged with special reference to illustrating the several features ofinvention as they may be applied in different cases,rathcr than any given set or order of train movements which may be effected thereby. I have not therefore shown my invention applied in full to any specific condition of tracks; but from the description of construction and operation herein given those skilled in the art to which it relates will be able to apply it as the various and continuually-changing conditions of use may require.

In the drawings, A represents a cast-metal base-plate, to the side edges of which are secured metal plates A. Along the inner faces of these side plates,near their central line,(see Fig. 4,) are thickened ledges or shoulders A, which receive and support a bed-plate, A of hard rubber, dry wood, or other suitable electric insulating material. At either end of this bed A cross-bars A (see Fig. 11) rest their ends upon the ledges A, and are secured in position by screw bolts. Along the inner lower edge of the cross-bars ledges or shoulders a project under the ends of the bed A andsupport the same. These end supports, a, may either be at intervals or may extend continuously across the bars, as in Fig. 11. Longitudinally-sliding bars B B B B B B",in any desired numbersix being shown in the present machine-are supported by the cross-bars A above the bed A", parallel therewith and with each other.

In order'to hold the sliding bars in proper relation to each other and to guide them in their movements, notches a are made in the upper face of the front and rear cross-bars, which notches receive the sliding bars, the latter being held down at the front by bar A, secured across and above the sliding bars by bolts aflscrewed into its ends through thesides A. Any desired number of these top bars may be placed at intermediate points along the sliding bars to prevent springing upward. Beneath the guide-notches a in the front crossbar, A, notches or openings to are made, which are somewhat narrower than the notches a, and are sunk to thelevel of the upper face of bed A. These lower notches, a, are designed to permit passage therethrough, when desired, of springs secured to the under face of the sliding bars,which springs will be hereinafter described.

Each of the bars 13 B &c., is moved longitudinally within its guides a by means of hand-levers A, connected thereto by end-pivoted rods a Sectors A on either side of each hand-lever guide the latter, and spring-latches a, taking into sector-notch a, afl'ord guidestops for setting the hand-levers and their respective sliding bars at intermediate positions or intervals of movement.

In order to limit the range or extent of movement of the sliding bars, stop-rods a are passed laterally through suitable holes, a, in the sector-plates, which arrest movement of the hand-levers. Any number of such holes may be made with reference to placing the stop a in any position that may be required by conditions of use.

Interlocking between the sliding bars B B 830., is effected as follows: Rocking bars 0 G C C C C, corresponding, as shown in the drawings, Fig. 7, to the number of sliding bars, are pivoted at their ends to side plates, A, by screw-bolts C, such bolts having their inner ends turned smooth to form pivots, which enter suitable holes, 0, in the ends of the bars. These pivot-centers are by preference in front of the central line of the bars. Springs 0 are secured at one end-say to the bed A-and at the other or upper end they press the under rear edge of the rocking bars 0 0 &c.. and thereby tend to lift such edge.

Arms c'one for each rocking bar-are secured thereto by screws, or in other convenient way, their positions being over the re spective sliding bars. These arms are extended over the front edge of the rocking bars and downward, resting at their lower eX- tremities upon the upper faces of the sliding bars. A notch, c", is made in the upper face of each sliding bar at such point in its length that when the bar is closed, or in its normal position, as the bars B 13 B 13, Fig. 7, the arm 0, riding on such bar, shall dropinto the notch, and thereby permit the springc to turn the rocking bar to horizontal position. \Vhen any one of the sliding bars is drawn out- ICO the end of arm a corresponding thereto is raised out of its notch, and the rear edge ofv its rocking bar is tipped down to or nearly to
